NEET BIOLOGY

Detailed explanation-1: -During photosynthesis, plants take in carbon dioxide (CO2) and water (H2O) from the air and soil. Within the plant cell, the water is oxidized, meaning it loses electrons, while the carbon dioxide is reduced, meaning it gains electrons. This transforms the water into oxygen and the carbon dioxide into glucose.

Detailed explanation-2: -Plants use photosynthesis to capture carbon dioxide and then release half of it into the atmosphere through respiration. Plants also release oxygen into the atmosphere through photosynthesis.

Detailed explanation-3: -Plants absorb carbon dioxide through small openings called stomata that are on the surface of the leaf.

Detailed explanation-4: -Plants take in – or ‘fix’ – carbon dioxide from the atmosphere during photosynthesis. Some of the carbon is used for plant growth, and some of it is used in respiration, where the plant breaks down sugars to get energy.

Detailed explanation-5: -Plants take in oxygen and give out carbon dioxide during respiration all the time.
